Any anime cons in Illinois?

Unfortunately I've never been to one and I've always wanted to. What better place to meet people like me than a place filled with people who love anime as much as I do!? I was wondering if anyone knows of any that are in Illinois? I would be very down to go with a bunch of new people, and make an adventure out of it! If you are interested please reply! Let's get out of our comfort zone and have fun doing what we love to do!
